I'm new to 3D printing and I recently got a LulzBot Taz 6 printer.
I'm interested in doing dual extrusion printing (especially with dissolvable supports), but I'm also interested in doing single extrusion prints. In particular, I would like to experiment with printing flexible filament.
The LulzBot TAZ Dual Extruder v3 Tool Head says that it can handle all the filament types that I am interested in.
Here is the question: can I use a dual extruder (in particular, the LulzBot TAZ Dual Extruder v3 Tool Head) for general purpose printing (read single extrusion) or do I need to use a single extrusion head for single extrusion print jobs.
If you can use a dual for single use, why buy single extruders (I've been looking at LulzBot TAZ Aerostruder Tool Head for flexy prints) if you can get the same performance out of a dual head?
If you should use a single extruder for non-dual prints, please explain the shortcomings of using a dual print head for general purpose use.
